Industrial and commercial users are required -- in accordance with the permit -- to control the quality of their discharge by installing appropriate treatment systems that will "pretreat" their wastewater prior to discharging to the sewer system.
Utilities will regulate this program with wastewater sampling and on-site inspections of commercial and industrial facilities -- both permitted and non-permitted.
The industrial pretreatment policy (click on online library, North Carolina, Charlotte and then search for Chapter 23, Article III) more clearly explains which customers must be permitted and the requirements of permitted customers. If you have questions about whether your business or industry should be permitted, call 704-336-4407 and ask for someone in industrial pretreatment.
Industrial pretreatment also has a septage receival program in place for septic tank waste, portable toilet waste and special industrial discharges. For more information about this program or for acceptance into this program, call 704-336-4407.
Industrial Waste Charges
Since wastewater from an industry or business costs more to treat -- even after it has been pretreated at the plant -- the business or industry must also incur the increased costs to the treatment plant. This ensures that proper measures are in place at the treatment plant to adequately treat the higher strength wastewater and that the added costs of this treatment are assumed by the appropriate users.
Commercial and industrial users are typically charged based on the type of establishment they are, not by their specific discharge. Customers should be given a classification code when they obtain a business license. This code will later be used to determine industrial waste charges, which are based on field sampling and laboratory analysis.
